Zusammenfassung: | PROBLEM TO BE SOLVED: To effectively execute cleaning before rolling in cold rolling of a stainless steel strip with a Sendzimir mill. SOLUTION: Spray nozzles 6 for removing foreign matters by blowing high- pressure water against the surface of the steel strips S are attached between the Sendzimir mill 2 and a wiping device 4. These spray nozzles 6 are connected to a liquid supply device of the separate system from the spray nozzles 5 for supplying rolling oil and the high-pressure oil is discharged under conditions that the pressure is >=10kg/cm and flow rate per mm is >=0.11/sec in the width direction. With this high-pressure oil, the cleaning of the surface of the steel strip S before rolling is executed. |
